Ultracold gases open new avenues to realize and explore key models of quantum physics. Using a set of interfering laser beams we created a honeycomb potential for a fermionic quantum gas. Going further beyond what is presently possible in solid-state experiments, we realized the topological Haldane model in this artificial graphene. It features topologically distinct phases of matter and provides a mechanism through which a quantum Hall effect can appear as an intrinsic property of a band-structure, rather than being caused by an external magnetic field.
